Chinese Houses or Colinsia heterophylla When you first see this plant in full bloom, you might think it was a Lupine and just go on your way. However if you took the time to look more carefully at this plant
you would see that the flowers form in a circle around the stalk (whorl is the precise term) and that these whorls of flowers decrease in size as you move up the
stalk to resemble a pagoda; hence the name Chinese Houses. The flowers have a lilac or white upper lip and a rose-purple or violet lower lip. On occasion these
flowers appear all white (upper and lower lips). The bright-green, lance-shaped (longer than wide) leaves clasp the stem.
I saw my first Chinese Houses of the 2015 season on the Pentachaeta Trail about half a mile in. There were three or four small spots where
the flower was growing. Looking around the area at the large amount of distinctive opposite paired leaves on the hundreds of plants it became
obvious that this bloom would soon begin in earnest - just not this day. Over the course of three weeks I re-visited the area and watched the flower
bloom as it stretched out alongside the trail back towards the trail head. What a pleasure to watch this play out! Another interesting fact - the leaves
turn a deep beautiful shade of Red at the end of the reproductive cycle. Click on the last picture to see what I mean. What a way to say goodbye to the early part of Spring.
Collinsia heterophylla is an annual plant growing in shady places, 10 to 50 centimeters (4 to 20 in) in height. It can be found in most of California
(other than desert regions) below about 1,000 meters (3,300 ft). Look for this plant along the edges of openings where there is some shade provided
by tall shrubs or trees or to be more specific: north-facing slopes in the bright shade of other plants. In most years this plant blooms from mid
Spring to early summer. Chinese Houses are somewhat unique among our wildflowers - they prefer shade - most of our native annual wildflowers thrive with lots of sunlight.
The stamens and pistils of this flower are hidden in away in the `keep`. If a pollinator lands on the flower the petal will lower and provide access to its pollen and nectar.
As the flowers mature, one can observe this `keep` (one of the photos shows this). The seeds need light as part of the germination process and will not germinate if
covered too deeply by soil.
Name Origin: Collinsia is in reference to Zaccheus Collins a Botanist who happened to be a Quaker, while heterophylla is in reference to the fact that this plant has two types of leaves on
the same plant: smooth edged and small toothed.
